Most of the Southern Alps started over 220 million years ago as sediment and rock on top of volcanic rocks on the seafloor. Intense heat and pressure consolidated the rock, and then uplifted it to form the
Main Divide. The present landscape was shaped by glacial processes during the
ice ages, when huge glaciers filled and scoured out the valleys. The area around Mount Aspiring, called Tititea by the
Māori, has a long history of Māori tribes coming from as far as Coastal Otago and the
Foveaux Strait to the inland lakes to collect
kākāpō,
kererū,
kākā and
tūī from the forest.
Moa would have also lived along the forest edges for the first 200 years of Māori settlement. The historic Māori
iwi (tribes) of
Kāti Māmoe and
Ngāi Tahu both had named settlements around the shores of Lakes Wānaka and
Hāwea, including Nehenehe on the northern banks of the mouth of the Matukituki River, which they called "Mātakitaki". Ovens for cooking
tī kōuka (cabbage tree) roots have been found at several sites on the lake shore.
Ngāi Tahu recorded Mātakitaki as a (food-gathering place) for (eels), (cabbage tree root), and (bracken fernroot). The first European to see Mount Aspiring was government surveyor
John Turnbull Thompson in 1857. The West Matukituki Valley was explored by
James Hector in 1862. Sheep and cattle farming began progressing up the valley in the 1870s. ==Fauna and flora==
